Paris at Work and Play

It's hard out here for an ex-con socialite! Paris Hilton spent her day shooting a music video at LaChappelle Studios, before deciding all that hard work deserved a little reward. Time for a vacation!

Later that day, the blonde whatever-she-is was back at her Hollywood manse packing up and jetting off to parts unknown. All the while, her precious new teacup Chihuahua was in hand. Hilton was heard remarking on the weather with her trademark phrase, saying, "It's hot!" That's hot.
